( Fig. 72 )

Stenolis Bates, 1864b: 149

Type species — Stenolis undulata Bates, 1864 (monotypy) [= Stenocorus angulatus Fabricius, 1801 ].

Nyssosternus Gilmour, 1963: 4 .

Type species — Nyssosternus duidaensis Gilmour, 1963 (original designation).

Nyssodectes Dillon, 1955: 142 . Syn. nov.

Type species — Nyssodectes veracruzi Dillon, 1955 (original designation).

Diagnosis. Prothorax without lateral tubercles, sides evently expanded backward; elytra without centrobasal crest or carinae. Number of species currently included: 24.

Remarks. Dillon (1955) reported on Nyssodectes : “Differs from all the other known genera of this group [“forms with a narrow prosternal process (not more than one-sixth as wide as a procoxal cavity), a subquadrate front, and an erect lower ocular lobe which is subequal to the gena in height”] in that the pronotum has a distinct basal sulcus and is unarmed laterally. Like Dectes and Canidia , this genus has the pronotal disk without tubercles, and the elytral basal gibbosities nearly wanting, but here the elytral apices are emarginate, with only the outer angle dentate, and the lower ocular lobe is subtriangular or broadly ovate.” Comparing the type species of Stenolis and Nyssodectes , it is not possible to find a reliable difference.Accordingly, Nyssodectes is considered a junior synonym of Stenolis . Even so, the species currently included in this genus have different morphological characters, especially the prothoracic shape, which may indicate that the genus is not monophyletic.
